Use Cases for Shop Floor Operator Support by means of Mixed Reality

The aim of this research is to explore the potential of Mixed Reality (MR) technologies for Operator Support in order to progress towards Industry 4.0 (I4.0) particularly for SMEs. Through a series of interventions and interviews conducted with local SMEs, potential use cases and their drawbacks have been identified. From this, insights were derived that serve as a starting point for conducting further experiments with MR technology in the smart manufacturing laboratory at the THUAS in Delft. The intervention consisted of a free form workshop in which the participants get ‘tinkering’ time to explore MR in their own work environment. The various levels of awareness were assessed in three stages: during an introductory interview, and after an instruction meeting and some ‘tinkering’. The study took place in the period from January 2022 to July 2022 with 10 local SMEs in the Netherlands. The results show that for all SMEs the awareness and understanding increased. The use cases identified by operators themselves concerned Quality Control, Diagnostics, Instruction, Specification and Improvement of Operations. Drawbacks foreseen related to Ergonomic Concerns, Resistance from operators, Technical considerations, Unavailability of MR device and an insufficient digital infrastructure to support MR in full extent. The use case most promising to the participants was further developed into a physical prototype for an ‘assisted assembly cell’ by which the aspects of ergonomics and the mentioned technical considerations could be analysed.

Uncertainty decomposed: Understanding levels of contingency to enable effective decision-making

Background: Uncertainty is a common challenge in managerial decision-making, especially when it comes to predicting future states, establishing cause-effect relationships, and having knowledge about relevant variables. However, it is difficult to deliberately address different types of uncertainty by applying specific decision-making strategies and hence enable reduction of uncertainty due to overlapping definitions and conflicting operationalization of the uncertainty construct. Purpose: The paper aims to delineate types of uncertainty along their epistemological configurations in terms of specific knowledge contexts to enable choices of suitable strategies for specific decision-making situations. Study design/methodology/approach: A literature review revises and discusses concepts of (un)certainty based on (im)perfect information and objectively/subjectively available assemblages of knowledge. Findings/conclusions: The paper provides a framework that encompasses and differentiates configurations of available information and knowledge applicable to decision-making situations. In order to achieve construct clarity and to free the original concept of uncertainty from conflicting definitions and heterogeneous operationalizations, the umbrella term contingency is introduced. It encompasses all states of (im)perfect information and variations in their epistemological configurations. Finally, the presented epistemological framework delineates levels of contingency along specific qualities of available information. The identified and discussed levels of contingency are certainty, risk, uncertainty in the narrow sense (i.n.s.), complexity, ambiguity/equivocality, and isotropy/radical uncertainty. The delineated levels of contingency help to tailor decision-making situation to specific epistemological configurations and hence may serve as a starting point for concluding and developing appropriate strategies to reduce contingency. Limitations/future research: A holistic understanding how to deal with and solve contingency requires further research focusing on aligning levels of contingency with strategies for decision-making (algorithms, causation, effectuation, bricolage, improvisation, trial & error) by taking types of knowledge (structural, procedural, conceptual) and contextual factors (e. g. time, [origin of] resources) into account.

Identifying factors affecting the selection of heads of city health centers in Iran: A phenomenological study.

Managers in the health care sector have the responsibility of accomplishing objectives and guaranteeing the excellence of services. To be chosen as a manager in a health organization, individuals must possess specific qualities and skills. Examining the process of selecting and appointing managers at the highest level of service provision might offer policymakers valuable insights into the importance of considering competences when choosing and appointing leaders of health centers. Hence, this study was conducted to identify the characteristics that influence the selection process of heads of city health centers in Iran. The present study employed a qualitative and phenomenological approach, utilizing interviews performed in the year 2023. The study sample consisted of health deputy from medical sciences universities, local health network managers, and heads of city health center. The participants were selected using a purposive selection method. A total of 16 male participants were interviewed, and the interviews were then analyzed using MAXQDA-10 software using the usual content analysis method. In this study, the factors affecting the selection of the heads of health care centers were classified into two general topics: individual factors and environmental factors, and eight sub-topics, including health literacy, experience, individual characteristics, communication skills, mental characteristics, legal issues, political factors, and cultural factors. The development of health literacy, specialized knowledge, and communication skills to coordinate and resolve organizational problems helps train competent managers. Top health system managers, who select health center managers, must understand political and cultural variables and regulate and steer their influence to select effective managers.

New CMS Merit-Based Incentive Payment System Value Pathway After Total Knee and Hip Arthroplasty: Preparing for Mandatory Reporting

This article discusses the implementation of a new Merit-Based Incentive Payment System Value Pathway (MVPs) applicable to elective total hip and total knee arthroplasty as created by Medicare and Medicaid Services (CMS) – the Improving Care for Lower Extremity Joint Repair MVP (MVP ID: G0058). We describe specific quality measures, surgeon-hospital collaborations, future developments with Quality Payment Program, and how lessons from early implementation will empower clinicians to participate in the refining of this MVP. The CMS has designed MVPs as a subset of measures relevant to a specialty or medical condition, in an effort to reduce the burden of reporting and improve assessment of care quality. Physicians and payors must be mindful of detrimental effects these measures in their current form may have on surgeons, institutions, and patients, including disincentivizing care for sicker or more vulnerable populations, and increased administrative costs. Early voluntary participation is crucial to gain valuable experience for the orthopedic community and in an effort to work alongside CMS to maximize care while minimizing cost for patients and burden for providers.

Impact of perioperative care and cognitive training on neurological recovery and life ability in hypertensive intracerebral hemorrhage patients undergoing minimally invasive hematoma evacuation.

To evaluate the effects of perioperative care combined with cognitive training on neurological recovery and life ability in patients with hypertensive intracerebral hemorrhage undergoing minimally invasive hematoma evacuation. A retrospective analysis was conducted using electronic records and data from patients treated at the Central South Hospital of Wuhan University from March 2022 to March 2023. The control group consisted of 44 patients receiving routine care, while the research group included 56 patients who received perioperative care combined with cognitive training. Baseline characteristics were analyzed, and neurological function, cognitive function, motor function, life ability, emotional status, and quality of life were assessed before and after intervention. Additionally, recovery time of gastrointestinal function, hospital stay, complications, and nursing satisfaction were compared between the groups. Post-intervention, both groups showed significant decreases in NIHSS (National Institutes of Health Stroke Scale), SAS (Self-Rating Anxiety Scale), and SDS (Self-Rating Depression Scale) scores (P<0.05), with the research group showing significantly lower scores than the control group (all P<0.05). Significant improvements in MMSE (Mini-Mental State Examination), ADL (Activities of Daily Living), SS-QOL (Stroke Specific Quality of Life Scale), and motor function scores were observed in both groups, with the research group achieving significantly higher scores (all P<0.05). The research group had shorter recovery time for gastrointestinal function, reduced hospital stays, and lower complication rates compared to the control group (all P<0.05). Nursing satisfaction was significantly higher in the research group (P<0.05). Logistic multivariate analysis identified hemorrhage volume and nursing methods as independent risk factors affecting prognosis (P<0.05). Perioperative care combined with cognitive training significantly enhances neurological recovery, cognitive function, motor ability, and overall life quality in patients with hypertensive intracerebral hemorrhage undergoing minimally invasive hematoma evacuation.

A 21st century-oriented model for the integration of foreign rule of law personnel and higher education in emerging technologies

Abstract Foreign-related rule-of-law personnel are an indispensable strategic resource for maintaining and expanding national interests, participating in the change of the international governance system, and providing important legal support for promoting the construction of a community of human destiny. This paper begins by outlining the objectives and strategies of training the foreign rule of law talents, describing the specific qualities of these talents, and establishing a “three-inone” foreign rule of law talents training model that integrates emerging information technology. The online learning big data platform for foreign rule of law talents provides the learning behavior data, which we weigh, process, and combine with the SHAP interpretable model to extract the learning behavior features. We used SMOTE to process data sampling imbalances and established a model for predicting student learning performance in combination with the XGBoost model. Additionally, we designed a comparative teaching experiment to analyze the teaching effect using the talent cultivation model. The SMOTE-XGBoost-SBD model yielded a coefficient of determination of 0.487, demonstrated a strong correlation between the predicted and actual performance, and yielded a SHAP value of 1.492 for the knowledge point mastery (C) characteristics of the foreign rule of law students. At the end of the teaching experiment, the mean value of the student’s performance in class A was 10.29 points higher than that in class B, and the average value of the student’s performance in class B was 10.29 points higher. The teaching experiment resulted in a mean score of 10.29 points higher for students in class A than for students in class B. 74.5% 7 of the students agreed with the “Trinity” foreign rule of law talent cultivation model. Using emerging information technology can foster the overall development of foreign rule-oflaw talents by integrating domestic and foreign legal resources.

Study on material-data-driven process parameterization in fine blanking

In industrial sheet-metal processing, processes are parameterized based on the material specifications. However, the manufacturing process of sheet-metal coils determines the material properties and as every manufacturing process is subject to variations, variations in material properties occur in the semi-finished product influencing the subsequent sheet-metal processing. The production of high-quality parts requires considering these varying material properties to adapt the processes accordingly. This paper shows that material data from non-destructive eddy current measurements and process data of the coil production enable decision support for the parameterization of fine blanking processes. A material-data-driven approach using material data recorded in an industrial setting is employed to investigate the influence of parameter settings in the fine blanking process on specific quality characteristics of fine blanked workpieces.

Особенности функционирования грифонимов в текстах англоязычных фэнтезийных видеоигр

The article highlights the results of a study on the cumulative functionality of fantasy character nominations in English-language video games. The relevant term “grifonym” is introduced for these nominations, proposed to denote quasi-anthroponyms of beings with a high degree of fictionality, possessing a one- or multi-component structural composition and relating to the appearance, unique characteristics, social role, activities, and origin of a fantasy character endowed with certain anthropomorphic traits. Considering the nature of the activities of grifonym bearers, it is established that, in addition to the universal nominative function, grifonyms in the accompanying texts of fantasy genre video games perform the function of conveying information about the specific qualities of the character (appearance, abilities, stage of evolution, etc.), the function of conveying information about the character’s habitat or fantasy locations, and the function of representing the referential correlation of grifonyms with real-world reality. The polyfunctional nature of grifonyms is noted, implying the simultaneous performance of two or more functions in the fantasy discourse. A conclusion is drawn about the significance of grifonym functionality in modeling fantasy realities, and prospects for further research development are outlined.

Evaluation of 2D ion chamber arrays for patient specific quality assurance using a static phantom at a 0.35 T MR-Linac

IntroductionPatient specific quality assurance (QA) in MR-Linacs can be performed with MR-compatible ion chamber arrays. However, the presence of a static magnetic field can alter the angular response of such arrays substantially. This works investigates the suitability of two ion chamber arrays, an air-filled and a liquid-filled array, for patient specific QA at a 0.35 T MR-Linac using a static phantom. MethodsIn order to study the angular response, the two arrays were placed in a static, solid phantom and irradiated with 9.96 × 9.96 cm2 fields every 10° beam angle at a 0.35 T MR-Linac. Measurements were compared to the TPS calculated dose in terms of gamma passing rate and relative dose to the central chamber. 20 patient specific quality assurance plans were measured using the liquid-filled array. ResultsThe air-filled array showed asymmetric angular response changes of central chamber dose of up to 18% and down to local 3 mm / 3% gamma rates of 20%, while only minor differences within 3% (excluding parallel irradiation and beams through the couch edges) were found for the liquid-filled ion chamber array without rotating the phantom. Patient plan QA using the liquid-filled array yielded a median local 3 mm / 3% 3D gamma passing rate of 99.8% (range 96.9%–100%) ConclusionA liquid-filled ionization chamber array in combination with a static phantom can be used for efficient patient specific plan QA in a single measurement set-up in a 0.35 T MR-Linac, while the air-filled ion chamber array phantom shows large angular response changes and has its limitations regarding patient specific QA measurements

Comparison of laparoscopic Heller myotomy and endoscopic balloon dilation in the treatment of achalasia: Effects on quality of life and patient satisfaction.

Achalasia is a rare neurodegenerative disease of the esophagus that causes impaired esophageal peristalsis and the inability of the lower esophageal sphincter (LES) to relax. This results in symptoms such as dysphagia, regurgitation, chest pain, and weight loss. Among the treatment options, Laparoscopic Heller Myotomy (LHM), Endoscopic Balloon Dilation (EBD), and Peroral Endoscopic Myotomy (POEM) are commonly used methods. The aim of this study was to compare the efficacy and clinical long-term results of LHM and EBD in treating achalasia. Patient records from Bezmialem Vakıf University Hospital were reviewed, and 36 patients diagnosed with achalasia who underwent LHM and EBD were included in the study. Patients were evaluated using the Pre-operative Eckardt Score (Pre-ES) for preoperative evaluation, the Post-operative Eckardt Score (Post-ES) for postoperative evaluation, the Achalasia Specific Quality of Life (ASQL) questionnaire, and the Patient Satisfaction Scoring (PSS). The mean age of the 19 patients who underwent LHM was 49.37±10.48 years. The mean age of the 17 patients who underwent EBD was 59.24±14.39 years. Perioperative complications included esophageal mucosal perforation in one patient in the LHM group, bleeding in three patients (17.64%), and esophageal perforation in one patient (5.88%) in the EBD group. At a mean follow-up of 90 months, gastroesophageal reflux developed in two patients (10.53%) in the LHM group and eight patients (47%) in the EBD group. The Pre-ES was similar in both groups. The Post-ES significantly decreased in the LHM group compared to the EBD group. When ASQL and PSS results were analyzed between the LHM and EBD groups, it was concluded that LHM was more effective than EBD in improving the quality of life and providing patient satisfaction (p-value: 0.001). In light of these findings, it was concluded that LHM is a safer intervention compared to EBD and should be prioritized, considering the low risk of complications, improved quality of life, and high level of satisfaction.

Pre-treatment expectations and their influence on subjective symptom change in Crohn's disease

BackgroundTreatment expectations reportedly shape treatment outcomes, but have not been studied in the context of multimodal therapy in Crohn's disease (CD). Therefore, the current study investigated the role of treatment expectations for subjective symptom changes in CD patients who have undergone an integrative multimodal therapy program. MethodsValidated questionnaires were completed at the start of the treatment program and post intervention. Pre-treatment expectations and experienced symptom change were assessed with the Generic Rating Scale for Previous Treatment Experiences, Treatment Expectations, and Treatment Effects (GEEE); stress levels were quantified with the Perceived Stress Scale (PSS-10) and disease specific quality of life was quantified with the disease-specific Inflammatory Bowel Disease Questionnaire (IBDQ). We performed multiple linear and Bayesian regression to determine how expectations related to symptom change. ResultsN = 71 CD patients (66.2% female) were included. Stronger expectations regarding symptom improvement (b = 0.422, t = 3.70, p < .001) were associated with higher experienced symptom improvement. Additionally, Bayesian analysis provided strong evidence for including improvement expectations as a predictor of improvement experience (BFinclusion = 13.78). ConclusionsIn line with research in other disorders, we found that positive treatment expectations were associated with experienced symptom improvement. In contrast, we found no indication that an experience of symptom worsening was associated with positive or negative baseline treatment expectations. Induction of positive expectations might be a potential avenue for improving treatment outcomes in CD therapy.

Trans Woman Voice Questionnaire Scores Highlight Specific Benefits of Adjunctive Glottoplasty With Voice Therapy in Treating Voice Feminization.

Treatment options to assist patients to produce a more perceptually feminine voice include voice therapy (VT) and surgeries to elevate pitch such as the Wendler glottoplasty (WG). The Trans Woman Voice Questionnaire (TWVQ) is a validated quality of life measure for trans women's self-reported perceptions of their voice and is frequently administered before and after such interventions. The 30 statements broadly pertain to how feminine a patient feels their voice is, how effortful it is to produce their voice, and how their voice impacts them psychosocially, making it a useful and specific outcome measure when treating trans females for voice concerns. To compare quality of life outcomes between VT and VT with adjunct WG (VT+WG) based on changes in ratings of individual statements on the TWVQ. A retrospective case series of 31 trans female patients treated was completed. A total of 17 patients underwent VT and 14 underwent VT with adjunctive WG. Ratings for each of the 30 TWVQ statements were compared before and after treatment for each group. Wilcoxon rank-sum tests were used to compare rating changes before and after treatment. Spearman rank-order correlation tests were used to assess the association between total TWVQ score and "current voice" rating. WG was associated with statistically significantly improved ratings for every statement on the TWVQ except one. In contrast, VT was associated with statistically significant improvements in 16 of the 30 statements, which largely pertained to patient emotions surrounding their voice rather than physical aspects such as pitch and dysphonia. Furthermore, while both WG+VT and VT improved the "current voice" rating significantly, WG improved the score by nearly 1 unit more. Lastly, we found a positive association between the total TWVQ score and current voice rating, indicating that lower scores were associated with more self-perceived feminine-sounding voices (P < 0.01). Both VT and VT+WG result in improvements in the TWVQ. The specific statements on the TWVQ offer insight into specific quality of life treatment outcomes, with VT associated with improvements in mostly psychosocial aspects of voice production and VT+WG with both psychosocial and physical aspects.

Ab. No. 167 Association between Balance, Cognition and Quality of Life in Middle Aged Postmenopausal Women: A Cross Sectional Study

Introduction: The hormonal changes occurring in women during and after menopause transition have a relevant impact on physical performance and health-related quality of life. The use of challenging balance conditions to detect sub clinical risk of balance impairment has been reported in aging population. Postmenopausal women may experience a decline in cognitive skills in their daily lives. A decrease in functional performance and cognitive function may lead to poor quality of life in postmenopausal women. There are studies reporting that low physical function can predict low cognitive function during menopause. The aim of the study is to find out association between balance, cognition and quality of life of middle-aged postmenopausal women. Methods: Middle aged 102 postmenopausal females aged 40-60years were included for study. A cross sectional study was conducted among 102 postmenopausal women who had natural history of menopause were included. Any women who had hysterectomy, hormonal replacement therapy, any severe musculoskeletal impairment, abnormal hearing and vision were excluded. Data was collected using the menopause specific quality of life questionnaire, timed up and go test for dynamic balance and Montreal cognitive assessment used for level of cognition. Result: Total 102 postmenopausal females aged 49.66±3.46 years. Mean scores for TUG (9.27 + 1.25), MOCA (21.46 + 2.90) and MENQOL (40.37 + 8.34) were seen. Correlation was found between TUG and MOCA were (p=.009) (r=.928), between TUG and MENQOL were (p=.056) (r=.574) and MENQOL with MOCA were(p=-.031) (r=.756) statistically significant. Conclusion: There is positive relationship between balance, cognition and quality of life is seen in middle aged postmenopausal females. Implications: Assessing and intervening early in the functional performance is essential to maintain and preserve cognitive function in aging by tailored cognitive motor training with holistic approach to maintain quality of life.

General self-efficacy as a moderator between severity of menopausal symptoms and satisfaction with life in menopausal women.

The study aimed to determine whether self-efficacy acts as a moderator between the severity of menopausal symptoms and life satisfaction. The research tools were: The Generalized Self-Efficacy Scale (GSES), The Satisfaction with Life Scale (SWLS) The Menopause - Specific Quality of Life (MENQOL), and a standardized questionnaire comprising questions on the participants' characteristics. 516 women using health care services who had menopausal symptoms took part in the study. Self-efficacy (GSES) (r = -0.176; p < 0.001) and life satisfaction (SWLS) (r = -0.106; p = 0.016) were negatively correlated with the severity of menopausal symptoms (MENQOL). The self-efficacy correlated positively with satisfaction with life (r = 0.278; p < 0.001). A low level of self-efficacy was associated with a significant and negative relationship between the severity of menopausal symptoms and satisfaction with life (p = 0.005), while at a high and moderate level of self-efficacy, the severity of menopausal symptoms was not associated with life satisfaction (p > 0.05). Self-efficacy moderates the relationship between the severity of menopausal symptoms and life satisfaction in menopausal women. The moderating function of self-efficacy is that, at its low level, an increase in the severity of menopausal symptoms reduces life satisfaction, while at medium and high levels, an increase in the severity of menopausal symptoms does not reduce life satisfaction.

Comparative Analysis of the Physico-Chemical Properties and Trace Metal Content of Palm Oil, from Selected Markets in Jos South and Jos North LGA, Plateau State, Nigeria.

The quality of palm oil samples collected from three different markets in Jos South and Jos North Local Government Area of Plateau State were analyzed and evaluated using standard analytical laboratory procedures. The relative ranges of the physicochemical values obtained were as follows; Moisture Content (MC): 0.56 - 1.89, Iodine value (IV); 51.88 - 55.57 g I2/100g, Peroxide Value (PV): 0.98 - 4.16 mEq02/kg, Saponification Values (SV): 198.46 - 201.54 mgKOH/g, Acid Value (AV): 9.93 - 57.65, and Refractive Index (RI), 1.4576 - 1.4580. The moisture content, iodin value, pH values and acid values were found to exceed the Standard Organization of Nigeria (SON) permissible limits of moisture content (0.29 mgKOH/g), iodine value (45 - 53 mg I2/100g), pH (5 - 7 mg/L), and acid value (0.7 max mg/L) for edible oils respectively while the refractive index, saponification values, peroxide values falls within the SON allowable limits of refractive index (1.4612-1.4707 mg/L), saponification value (195-205 mgKOH/g) and peroxide value (10 mEq02/kg) respectively . The amounts of trace metals (Cu, Zn, Fe, Pb and Cd) determined in the palm oil using the atomic absorption spectrophotometer ranged from Cu(0.34 - 0.52 mg/l), Zn(1.58 - 2.33 mg/l), Fe(19.18 - 26.74 mg/l), Pb(2.87 - 4.06 mg/l) and Cd(1.58 - 2.24 mg/l). However, the levels of Zn, Fe, Pb and Cd exceeded the WHO/FAO recommended values of (1.50, 1.00, 0.05 and 0.02 mg/L) respectively while only Cu concentration was below the WHO/FAO limits of 2.00 mg/L for trace metals in edible palm oil. Consequently, the results of this study shows that the palm oil consumed from these selected markets does not meet the standard quality specification for edible palm oils and hence can post significant health threat to consumers. Therefore, food regulatory agencies should strengthen their surveillance to promote food and health safety of the populace.
